Description

Technical Field

[0001] This application relates to the field of idler rollers for belt conveyors, and in particular to a high-efficiency dewatering idler roller for belt conveyors that can be used without stopping. Background Technology

[0002] Belt conveyors, when transporting materials containing moisture or during rain or snow, often accumulate water on the conveyor belt. This water accumulation causes several problems. The water reduces the coefficient of friction between the material and the conveyor belt, leading to slippage and spillage when the material is conveyed at an angle. Therefore, timely removal of water from the conveyor belt is crucial for the safe operation of the belt conveyor and the smooth transport of materials.

[0003] Currently, two common drainage methods are used: belt lifting and belt pressing. The belt lifting method is more prevalent in industrial and mining sites, where the conveyor belt is raised from below to flatten it and achieve drainage. However, this method results in the raised section of the conveyor belt being higher than the rest, causing water to flow along the trough-shaped conveyor belt to low-lying areas, leading to poor drainage. The belt pressing method, on the other hand, involves pressing down the edges of the conveyor belt to lower it below the water surface to achieve drainage. Both methods require equipment shutdown, are time-consuming and labor-intensive, and increase operating costs. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a high-efficiency dewatering idler for belt conveyors that does not require shutdown.

[0005] A non-stop high-efficiency dewatering idler for a belt conveyor, used for dewatering on the return section of the conveyor belt, comprising:

[0006] The idler body has a radial cross-section and includes multiple scrapers. The scrapers are arranged in a circumferential array and extend in a direction away from the axis of the idler body. Two adjacent scrapers can simultaneously abut against the conveyor belt. The scrapers are elastic in the return movement direction of the conveyor belt.

[0007] A rotating shaft, coaxial with and passing through the idler body, and...

[0008] A support base is located at both ends of the rotating shaft and is fitted onto the rotating shaft. The support base can drive the rotating shaft to rotate.

[0009] By adopting the above solution, if there is water on the conveyed material, water will remain on the conveyor belt. The remaining water will adhere to the conveyor belt. When the conveyor belt moves to the return section, the idler roller body rotates under the drive of the support seat during the movement of the conveyor belt. During the rotation of the idler roller body, the scraper on the idler roller body will rub against the conveyor belt. During the friction process, the scraper fully contacts the surface of the conveyor belt and scrapes off the water on the surface of the conveyor belt. Because the scraper is elastic, when the scraper leaves the surface of the conveyor belt, the scraper will rebound and bounce off the water.

[0010] In one embodiment, the scraper has a friction part on the side opposite to the rotating shaft, and the friction part has a circular cross-section.

[0011] By adopting the above solution, the friction part can make smooth contact with the conveyor belt, avoiding the scraper from scratching the surface of the conveyor belt.

[0012] In one embodiment, the surface of the friction part is covered with a cleaning felt.

[0013] By adopting the above solution, the scraper can remove residual water from the surface of the conveyor belt while also cleaning the surface of the conveyor belt.

[0014] In one embodiment, the friction part is made of absorbent sponge material.

[0015] By adopting the above solution, while the friction part rubs against the surface of the conveyor belt, it can also absorb moisture from the surface of the conveyor belt, thereby enhancing the water removal and cleaning effect of the friction part.

[0016] In one embodiment, the roller body further includes a plurality of extrusion devices, each of the scrapers corresponding to the extrusion device, which can squeeze out moisture from the friction part.

[0017] By adopting the above solution, the friction part can be kept dry, allowing it to repeatedly absorb water.

[0018] In one embodiment, the extrusion device includes a connecting plate, a receiving groove, and a driving sleeve. The connecting plate is located in the receiving groove and fixed to the bottom of the friction part. The connecting plate has L-shaped connecting rods at both ends that are connected to the driving sleeve. The driving sleeve is located at the bottom of the receiving groove and sleeved on the scraper. The driving sleeve is slidably connected to the scraper. The receiving groove is fixed to the side of the scraper away from the rotating shaft and its width is smaller than the diameter of the friction part.

[0019] By adopting the above solution, the drive sleeve can move with the connecting plate by sliding the drive sleeve away from the friction part. The connecting plate can bring the friction part into the receiving groove, and the receiving groove squeezes the friction part, thereby squeezing out the moisture absorbed in the friction part and keeping the friction part dry.

[0020] In one embodiment, the sidewall of the receiving groove is provided with a squeezing roller, and the squeezing roller includes a plurality of rollers, with the topmost squeezing roller abutting against the bottom of the friction part.

[0021] By adopting the above solution, the friction between the friction part and the side wall of the receiving groove is reduced, thereby enhancing the extrusion efficiency of the receiving groove.

[0022] In one embodiment, the drive sleeve includes a sliding roller and a connecting block, and there are two sliding rollers and two connecting blocks. The sliding rollers are located on both sides of the scraper, and the connecting blocks are located at both ends of the sliding rollers and are rotatably connected to the two sliding rollers.

[0023] By adopting the above solution, the friction between the drive sleeve and the scraper is reduced, allowing the drive sleeve to slide smoothly along the scraper.

[0024] In one embodiment, the drive sleeve is connected to the bottom of the receiving groove via an elastic element.

[0025] By adopting the above scheme, the drive sleeve has a reset effect. When the friction part is stuck in the receiving groove, the drive sleeve can apply an upward thrust to the friction part, thereby pushing the friction part out of the receiving groove.

[0026] In one embodiment, the support base is provided with a guide plate, the guide plate is provided with a guide hole, the guide hole is circular, the center of the guide hole is located above the axis of the rotating shaft, and the connecting block is provided with a guide rod that slides along the guide hole.

[0027] By adopting the above scheme, when the guide rod rotates to the top of the guide hole, the elastic element is in a natural state. When the guide rod rotates to the bottom of the guide hole, since the center of the guide hole is located above the axis of the rotating shaft, the guide rod will cause the drive sleeve to shift. The distance between the center of the guide hole and the axis of the rotating shaft is the sliding distance of the drive sleeve. The drive sleeve drives the friction part to move into the receiving groove through sliding. The friction part is squeezed by the receiving groove to expel water.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When there is water on the material of the conveyor, the water will adhere to the conveyor belt. By setting elastic scrapers on the outer circumference of the idler roller, the idler roller body is placed in contact with the surface of the conveyor belt on the return part. During the rotation of the idler roller body, the scraper on the idler roller body will rub against the conveyor belt. During the friction process, the scraper fully contacts the surface of the conveyor belt and scrapes off the water on the surface of the conveyor belt. Because the scraper is elastic, when the scraper leaves the surface of the conveyor belt, the scraper will bounce back and knock off the water, thus achieving dehydration of the conveyor belt.

[0030] 2. By setting a connecting plate, a receiving groove, and a driving sleeve on the scraper, the driving sleeve can move the connecting plate by sliding the driving sleeve away from the friction part. The connecting plate can bring the friction part into the receiving groove, and the receiving groove squeezes the friction part, thereby squeezing out the water absorbed in the friction part and keeping the friction part dry.

[0031] 3. By setting a guide plate with a drive guide hole on the support base, when the guide rod rotates to the bottom of the guide hole, since the center of the guide hole is located above the axis of the rotating shaft, the guide rod will drive the drive sleeve to shift, and the elastic element will be in a stretched state. The distance between the center of the guide hole and the axis of the rotating shaft is the sliding distance of the drive sleeve. The drive sleeve drives the friction part to move into the receiving groove through sliding. The friction part is squeezed by the receiving groove to expel water. When the guide rod continues to rotate to the top of the guide hole, the elastic element is in a natural state, and the friction part is located outside the receiving groove, thus rubbing against the surface of the conveyor belt to absorb the water accumulated on the surface of the conveyor belt, realizing automatic water absorption and dehydration.

[0039] Therefore, it is necessary to provide a high-efficiency dewatering idler for belt conveyors that can remove residual water from the surface of the conveyor belt without stopping.

[0040] Example 1

[0041] Please refer to the following: Figure 1 , Figure 1 This is a schematic diagram of the structure of a non-stop high-efficiency dewatering idler for a belt conveyor according to the first embodiment of this application, including an idler body 2, a rotating shaft 3, and a support base 4.

[0042] The idler roller body 2 is a structure composed of radially extending scrapers 21. Each adjacent scraper 21 can abut against the conveyor belt 1, ensuring full contact with the surface of the conveyor belt 1 during rotation. The scrapers 21 can be made of rubber or other materials with good elasticity and wear resistance to ensure durability and stability during long-term use. For example, natural rubber or synthetic rubber can be chosen as the material for the scrapers 21, or polyurethane can be selected, the latter having better oil resistance and tear resistance. The rotating shaft 3 is one of the core components of the idler roller body 2; it passes through the center of the idler roller body 2 and is arranged coaxially with it. Both ends of the rotating shaft 3 are connected to the support seat 4 via bearings to ensure smooth operation. To improve the strength and rigidity of the rotating shaft 3, high-strength alloy steel or stainless steel can be used to manufacture it. Furthermore, chrome plating or an anti-corrosion coating can be applied to the surface of the rotating shaft 3 to extend its service life.

[0043] A friction part 211 is provided on the side of the scraper 21 opposite to the rotating shaft 3. The friction part 211 has a circular cross-section. The main function of the friction part 211 is to increase the friction force when the scraper 21 contacts the conveyor belt 1, preventing the scraper 21 from scratching the surface of the conveyor belt 1. The friction part 211 can be made of various materials, such as hard plastic, nylon, or composite materials. These materials all have good wear resistance and low coefficient of friction, which can effectively protect the conveyor belt 1 from damage. The friction part 211 can be fixed to the back of the scraper 21 by adhesive or by mechanical fasteners. The shape of the friction part 211 can be adjusted according to actual needs. In addition to circular, it can also be designed as an ellipse or polygon, or other geometric shapes. This not only increases the friction area but also helps to disperse pressure, further reducing the potential risk of damage to the conveyor belt 1.

[0044] A cleaning felt can be fitted onto the surface of the friction part 211. The cleaning felt is a soft material with high water absorption capacity, which absorbs and removes moisture and impurities from the surface when the scraper 21 contacts the conveyor belt 1. The thickness of the cleaning felt is generally between 1-3 mm and can be adjusted flexibly according to actual working conditions. For example, for materials with high moisture content, the thickness of the cleaning felt can be appropriately increased; while for materials with low moisture content, the cleaning felt can be thinned to improve the working efficiency of the scraper 21. The cleaning felt can be made of materials such as wool, polyester fiber, and cotton fiber. These materials all have good water absorption and breathability, allowing them to remain dry while scraping away moisture. Furthermore, the cleaning felt can be cleaned or replaced regularly to ensure it always maintains optimal working condition.

[0045] Support bases 4 are located at both ends of the rotating shaft 3, and are fitted onto the rotating shaft 3. The function of the support bases 4 is to support the rotating shaft 3 and drive its rotation. An electric motor or hydraulic motor is installed inside the support base 4, which transmits power to the rotating shaft 3 through a reducer. The outer shell of the support base 4 is made of cast iron or aluminum alloy, ensuring sufficient strength while reducing weight. To reduce noise and vibration, sound-insulating material can be filled inside the support base 4, and shock-absorbing pads can be installed in key areas.

[0046] Please refer to the following: Figure 2-3 , Figure 3 This is a partial diagram illustrating the working principle of a non-stop high-efficiency dewatering idler for a belt conveyor according to this application. The working principle of this embodiment is as follows: water accumulates on the conveyor belt 1. The dewatering idler is placed on the return section of the conveyor belt 1. The support base 4 drives the rotating shaft 3 to rotate. The scraper 21 on the outer circumference of the dewatering idler is deformed by the pressure of the conveyor belt 1. Due to the elastic force, the scraper 21 comes into close contact with the surface of the conveyor belt 1, thereby generating sufficient friction with the surface of the conveyor belt 1. During the friction process, the scraper 21 comes into full contact with the surface of the conveyor belt 1, scraping away the water accumulated on the surface of the conveyor belt 1. Because the scraper 21 is elastic, when the scraper 21 leaves the surface of the conveyor belt 1, the scraper 21 will rebound, knocking the water off, thus achieving dewatering of the conveyor belt 1.

[0047] Example 2

[0048] Please see Figure 4-5 , Figure 4 This is a schematic diagram of the structure of a high-efficiency dewatering idler for a belt conveyor according to the second embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiment, except that the idler body 2 also includes multiple squeezing devices 5. The main purpose of the squeezing devices 5 is to squeeze out the water absorbed in the friction part 211, keep the friction part 211 dry, and thus enable the friction part 211 to repeatedly absorb water. Each scraper 21 corresponds to a squeezing device 5, which mainly includes three parts: a connecting plate 51, a receiving groove 52, and a drive sleeve 53.

[0049] The connecting plate 51 is located within the receiving groove 52 and fixed to the bottom of the friction part 211. L-shaped connecting rods 511 are provided at both ends of the connecting plate 51, and the other end of each L-shaped connecting rod 511 is connected to the drive sleeve 53. The drive sleeve 53 is located at the bottom of the receiving groove 52 and is fitted onto the scraper 21; the two are slidably connected to achieve relative movement. The receiving groove 52 is fixed to the side of the scraper 21 opposite to the rotating shaft 3, and its width is smaller than the diameter of the friction part 211, so that the friction part 211 can be completely pressed into the receiving groove 52 when the drive sleeve 53 slides.

[0050] As the drive sleeve 53 slides along the scraper 21, it drives the connecting plate 51 to move via the L-shaped connecting rod 511. The connecting plate 51 then pushes the friction part 211 into the receiving groove 52. At this time, the receiving groove 52 squeezes the friction part 211, forcing out the water. To avoid excessive pressure on the friction part 211 during the squeezing process, the side wall of the receiving groove 52 is provided with multiple rolling squeezing rollers 521. These squeezing rollers 521 can reduce the friction between the friction part 211 and the receiving groove 52, improving the squeezing efficiency. In addition, the drive sleeve 53 is connected to the bottom of the receiving groove 52 via an elastic element 54. When the friction part 211 gets stuck in the receiving groove 52, the drive sleeve 53 can apply an upward pushing force to help the friction part 211 return to its initial position. This self-resetting mechanism ensures the continuity and reliability of the squeezing device 5.

[0051] The working principle of this embodiment is as follows: by sliding the drive sleeve 53 away from the friction part 211, the drive sleeve 53 can move the connecting plate 51. The connecting plate 51 can bring the friction part 211 into the receiving groove 52. The squeezing roller 521 in the receiving groove 52 squeezes the friction part 211, thereby squeezing out the moisture absorbed in the friction part 211 and keeping the friction part 211 dry.

[0052] Example 3

[0053] Please see Figure 6 , Figure 6This is a schematic diagram of the structure of a non-stop high-efficiency dewatering idler for a belt conveyor according to the third embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiments, except that the support base 4 is provided with a guide plate 41, and the guide plate 41 has a guide hole 411. The guide hole 411 is circular and its center is located above the axis of the rotating shaft 3. The connecting block 532 is provided with a guide rod 5321, which can slide along the inner wall of the guide hole 411. When the guide rod 5321 rotates to the top of the guide hole 411, the elastic element 54 is in a natural state, and at this time the guide rod 5321 is in contact with the inner wall of the guide hole 411. When the guide rod 5321 rotates to the bottom of the guide hole 411, since the center of the guide hole 411 is located above the axis of the rotating shaft 3, the guide rod 5321 will drive the drive sleeve 53 to shift, and the elastic element 54 will be in a stretched state. The distance between the center of the guide hole 411 and the axis of the rotating shaft 3 is the sliding distance of the drive sleeve 53.

[0054] The working principle of this implementation is as follows: During the rotation of the idler body 2, the guide rod 5321 slides along the inner wall of the guide hole 411. When the guide rod 5321 is at the top of the guide hole 411, it naturally contacts the side wall of the guide hole 411, and the drive block will not pull the L-shaped connecting rod 511. When the guide rod 5321 rotates to the bottom of the guide hole 411, since the center of the guide hole 411 is located above the axis of the rotating shaft 3, the guide hole 411 will apply upward pressure to the guide rod 5321. At this time, under the drive of the guide rod 5321, the drive block will pull the L-shaped connecting rod 511, thereby pulling the friction part 211 into the receiving groove 52 for squeezing and dehydration. When the idler body 2 continues to rotate, the dehydrated friction part 211 rotates to the top of the guide hole 411 and absorbs the moisture on the surface of the conveyor belt 1, so that the friction part 211 remains dry during the rotation of the idler.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
